automation

In some situations, it can be useful to simulate user events on a keyboard or mouse, without an actual keyboard or mouse. The original idea that made me look into this subject, was that I wanted to run RetroPie on my Raspberry Pi with different ways to control the system. Instead of a keyboard, I wanted to use GPIO inputs (buttons or joysticks), or even a web interface that I could access from my phone. We’ll use a program called xdotool to do this.
